Concept of LoRa Transmitter, BME280 Sensor and WiFi Webserver based on Arduino ESP32 (EP07)
(1/7) Ideas, tutorials and fun around electronics. Regular episodes are occasionally complemented by free downloads. This episode is the first one for a little LoRa project, sharing the concept. Two sensor (BME280 for temperature, humidity, pressure) units are transmitting their measurements via LoRa (Long Range) to a receiver unit, which comprises a a simple web server. The server is storing data for the whole year, computing mean, minimum, maximum values etc. The data can be accessed either via WiFi with any web browser or via the serial USB interface of the ESP32 processor. The code is written in C++ using the Arduino platform.
